3 Claims.

My invention relates to chair swings of the type adapted for use onporches and lawns.

It is the object of my invention to provide a swing of this type soconstructed as to be knocked down or collapsed into a small compass forshipping or storage purposes and which when set up shall possess greaterstrength andrigidity with a greater freedom of movement than swings ofconventional construction. Other and more specific objects of myinvention will be apparent from the following specification and claims.

In th accompanying drawings which illustrate one embodiment of myinvention:

Fig. 1 is a side elevation; Fig. 2 is an end elevation; Fig. 3 is adetail section on line 3--3 of Fig. 2; Fig. 4 is a detail section online 4.-4 of Fig. 1; Fig. 5 is a detail section on line 55 of Fig. 2;Fig. 6 is a plan View of the floor assembly; Fig. '7 is a detail sectionon line 77 of Fig. 6; Fig. 8 is a detail section on line 88 of Fig. 6;Fig. 9 is a side elevation showing a modified form;

Fig. 1D is an end elevation of the structure shown in Fig. 9;

Fig. 11 is a plan view of the floor assembly of the structure shown inFigs. 9 and 10;

Fig. 12 is a detail section on line 12-12 of Fig. 11;

Fig. 13 is a detail section on line 13-13 of Fig. 11;

Figs. 1 1 and 15 are detail views on a smaller scale showing one mannerof connecting the frame to other uses; and

Figs. 16 and 17 are fragmentary details of an alternative form ofhanger.

As shown in the drawings, the swing comprises a stationary frame formedby four inciined members 1 connected to form respective end pairs by capmembers 2 and 3. The cap members are secured to the inclined members bymeans of angle irons 5 and bolts 6. The connection of the cap members tothe inclined members is braced and made rigid by suspension irons Swhich may be secured in place by separate bolts but preferably are heldby the bolts .6 remote from the intersection of the inclined members andcap members. Crossed side members 9 connect the side pairs of inclinedmembers 1. The upper'ends of the crossed members are held by the bolts 6which hold the adjacent suspension irons 8 to the inclined members whiletheir lower ends are secured to the adjacent inclined member by bolts10. The crossed side members are held together at their intersection bybolts 12. Foot members 13 and 14 respectively connect the end pairs ofinclined members 1 by means of angle irons 16 and bolts 1'7, as shown indetail in Fig. 5.

The swing proper is supported by suspension 'gitudinal member 41.

members 19. The suspension members are freely hung on the suspensionirons 8 by means or" pear shaped apertures formed in one end of themembers. The upper portion 20 of these apertures snugly fits the irons8, as best'shown in Fig. 3, while the lower portion 21 is madesufficiently large to permit passage of the looped end of the suspensioniron during assembly. The ends of the suspension members are reinforcedby bolts 22.

The side pairs of the suspension members are respectively connected attheir lower ends by spanner members 23 and 24. This connection is madeby means of bolts 25 provided with sleeves 26 (see Fig. 4), permittingeasy pivotal movement between the suspension and spanner members. Eachend pair of suspension members 19 supports a chair formed by chair backmembers 27 pivoted at their lower end to the adjacent suspension memberby the sleeved bolts 25 previously mentioned. Slatted chair backs,formed of slats 28 nailed or otherwise permanently secured to sidepieces 29 are secured between the members 27, as best shown in Fig. 2,by bolts 30, the slats 28 extending over the members 27 to preventturning of the backs about bolts 30 and to give added rigidity to theassembly. Seat members 31 connect each chair back member 27 to itsadjacent suspension member, members 31 being secured to members 27 bybolts 32 and to suspension members 19 by bolts 34. Bolts. 34 also passthrough side members 35 to which are nailed or otherwise permanentlysecured slats 36, forming unitary slatted seat members.

The floor of the swing, as best shown in Fig. 6, is made in twosections, spanner 23 forming a permanent part of one section and spanner24 a permanent part of the other. Slats 38 are nailed or otherwisepermanently secured to spanner 23 and a longitudinal member39. Slats 40are similarly secured to spanner 24 and a lon- As best shown in Figs. 6and 7, longitudinal members 39 and 41 are provided at their ends withrectangular hooks 43 engaging over transverse members 44 and 45 whichare provided on their ends with similar hooks 46 engaging spannermembers 23 and 24. As shown in Fig. 8, hooks 46 are slightly wider thanthe spanners. This is desirable to permit the hooks to rock slightlyabout the spanner securing a greater ease in assembly, particularlywhere the parts are too stiff to permit them to be sprung into place.

In the modified structure of Figs. 9 to 15, inclusive, are disclosedalternative and modified forms of construction and assembly which havecertain advantages from the viewpoint of construction cost andinterchangeability of parts, thus increasing the field of use. As in theform previously described, no dowels or tenons are necand swing membersbeing assembled in face to face or surface contact.

Referring now particularly to Figs. 9 and 10, 51 designates fourinclined members connected at their upper ends, to form respective endpairs, by cap members 52 and 53. As will be clear from a comparison ofFigs. 1 and 9, the members 51 of each pair face the opposite pairflatwise. This permits the use of ordinary bolts 54 for fastening thecap members 52 and 53 to members 51, as well as for securing the footmembers 55 and 56 to members 51. The frame proper is completed by crossbraces 57 and 58 secured to opposite end members 51 by means of suitablyshaped channeled angle irons 59 and bolts 60.

The swing is supported by suspension members 61 provided at their upperends with channel irons 62, secured by bolts 63. Members 61 are hungfrom brackets 65 bolted at 63' to the cap members and are pivoted inslots 64, formed in the depending brackets 65, by bolts 66.

The side pairs of the suspension members 61 are respectively connectedat their lower ends by spanner members 67 and 68. This connection ismade by means of sleeved bolts '70 permitting easy pivotal movementbetween the suspension and spanner members. Each end pair of suspensionmembers 61 supports a chair formed by back members '11 and seat members'72 bolted together as in the construction first described, andsimilarly provided with slatted back and seat units 73 and '74respectively. In the modified form now being described, the floor of theswing (see Figs. 9 and 11) is formed of two transverse sections '76which are exactly similar and formed from pieces having the samedimensions as back and seat units '73 and '74 and are interchangeablewith the seat members '74. As best shown in Figs. 11, 12 and 13, theslats of the floor are reinforced by a central piece '77 provided ateach end with a cross piece '78. Pieces '78 are provided with hooks '79engaging over spanner members 6'7 and 68. The end pieces 78 arepreferably pivoted as at 80 to the central piece '77 so that the endpieces may be pivoted into alignment with the central piece forshipping.

As indicated in Figs. 14 and 15, suspension members 61 may be easilyreplaced by longitudinal beams 82 provided with vertical irons 83 whichare adapted to be held in brackets 65 by the bolts 66 in the same manneras were the irons 62 of the suspension members 61. Beams 82 may beprovided with a trapeze 85 and flying rings 86 or other apparatus toconvert the swing into a playground gymnasium.

In Fig. 16 is shown a modified form of bracket or hanger 90 which mayreplace bracket 65 above described. Hanger 90 is simpler in form and ispivoted to iron 62 of the suspension member 61 by a rivet or short bolt91.

In Fig. 1'7 is shown an alternative manner of connecting suspensionmembers 19 to irons 8, which comprises a slotted iron 15 bolted to theend of the suspension members 19.

It will be seen from the above description that all the frame and swingmembers are assembled in face-to-face contact, and that no dowels ortenons are used in the construction of the swing, yet a more rigid andsturdy structure is secured than by the conventional practice. The swingcan be completely knocked down for shipment or storage to form a packagehaving a maxi mum length equal to the length of inclined members 1 or 51and a maximum width equal to that of the slatted seat units. Thecomplete absence of dowels or tenons also greatly simplifies themanufacture and finishing of the parts.
